摘要
韩江特大桥V型墩顶主梁0号块长17.2 m,其施工支撑体系由贝雷钢桥、钢管立柱等构成,体系支承于8.0 m长的承台和施工钢平台上。通过理论计算,所设计的支撑体系满足要求,实践证明该体系经济合理,方便施工。
0# block of V-type pier cap main beam in Hanjiang extra-long bridge is of 17.2 m. Its construction support sys- tem is composed of Bailey steel bridge, steel pipe pillar, which is supported by 8.0 m cushion cap and construction steel platform. Through theoretical calculation, designed support system meets the requirements. Practice also proves the economy and rationality of this system, and its convenience for construction.
